7017 CE/P4ALDBB Bearing Product Overview & Core Advantages
The 7017 CE/P4ALDBB is a precision duplex angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high rigidity. This matched back-to-back (DB) arrangement is preloaded to Light / Class B specifications, providing superior system stiffness and minimizing axial and radial runout. Its primary advantage lies in its ability to handle combined loads (radial and axial) simultaneously with high precision, making it ideal for high-speed, high-rigidity spindles and precision machinery where operational stability is critical.
7017 CE/P4ALDBB Bearing Model Code Explained, Specifications & Naming Convention
The model number 7017 CE/P4ALDBB provides detailed technical specifications:
- 7017: Standard bore (85 mm), outside diameter (130 mm), and width (44 mm) dimensions.
- C: Represents a 15° contact angle, optimized for handling axial loads.
- E: Indicates optimized internal design, often for higher speeds and reduced friction.
- P4A: Denotes a very high precision tolerance class, exceeding ABEC 7 standards, ensuring minimal dimensional variation and superior running accuracy.
- L: Signifies Light preload applied to the bearing set.
- DB: Stands for Duplex Back-to-Back arrangement. This configuration increases moment rigidity and is excellent for applications with overturning moments.
7017 CE/P4ALDBB Bearing Structural Features & Performance Benefits
The performance of the 7017 CE/P4ALDBB is a direct result of its advanced construction:
- High Rigidity & System Stiffness: The duplex back-to-back (DB) arrangement and light preload create a highly rigid bearing system that effectively resists operational deflection and moment loads, ensuring precise tool or shaft positioning.
- Superior Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers high dynamic and static load ratings, reliably supporting significant combined radial and axial loads.
- High-Speed Capability: The phenolic resin cage is lightweight and robust, contributing to lower centrifugal forces, reduced friction, and stable operation at high rotational speeds, with a limiting speed of 28,000 rpm.
- Precision Performance: The P4A tolerance class guarantees extremely tight dimensional and running accuracy, which is essential for applications demanding minimal vibration and high positional accuracy.
7017 CE/P4ALDBB Bearing Typical Application Areas
